说明
apptainer config manages configuration for the Apptainer container platform. It provides administrative commands for managing fakeroot user mappings and editing the global apptainer.conf configuration file from the command line. Most operations require root privileges or an unprivileged installation. The command operates through two subcommands: fakeroot for managing user namespace mappings that allow unprivileged users to build and run containers with apparent root access, and global for modifying system-wide configuration directives that control container behavior, bind paths, security settings, and resource limits.
